German solar industry study: grid batteries could unlock 150 GW capacity

BSW-Solar-commissioned research suggests intelligent battery storage at substations could dramatically expand solar capacity without requiring massive grid upgrades.

What to know

  • Study commissioned by German solar industry claims battery storage at 1,313 substations could unlock 150 GW of additional solar capacity—exceeding current total German solar output.
  • Intelligent battery management would reduce annual solar curtailment to ~1%, compared to current grid constraints that occur at peak times.
  • BSW-Solar opposes government's pending grid package (Netzpaket), arguing it imposes network congestion restrictions rather than optimizing existing spare capacity.
  • Proposal hinges on digital control systems that capture peak solar generation and release power during evenings and nights, avoiding large-scale grid infrastructure upgrades.

    BSW-Solar criticizes pending grid package as overly restrictive

    The association argues the government's forthcoming grid package (Netzpaket) under parliamentary review would designate large parts of Germany as network congestion areas, effectively halting renewable expansion via planned redispatch measures. BSW-Solar instead advocates digitizing existing networks, streamlined procurement of intelligent storage systems, and utilizing spare capacity rather than imposing new restrictions.

      Noch einmal - und wieder mit harten Fakten unterlegt: Wir brauchen Ihr Gas nicht, Frau Reiche! Orientieren Sie sich endlich an den Fakten der Wissenschaft - und nicht den finanziellen Interessen Ihrer früheren(?) Auftraggeber!

      Ach? Wenn man mit #Batteriespeichern den tagsüber erzeugten PV-Strom im lokalen Netzabschnitt lagert, um ihn dann Abends und nachts zu verbrauchen, dann werden die Netze entlastet? Das wird in Australien seit ein paar Jahren konsequent ausgebaut…

  2. background

    Study details efficiency gains: only 1% of solar curtailed under battery scheme — The research reveals that with intelligent battery management, only about 1% of additionally generated solar power would need to be curtailed annually due to transformer capacity limits. Currently, transformers are constraint-limited only at certain times; batteries could allow substations to accept more than double the renewable capacity the transformer can transmit by capturing peaks and releasing power later.

    BSW-Solar study finds battery storage can unlock 150 GW solar capacity

    The Bundesverband Solarwirtschaft (BSW-Solar) released findings from Fraunhofer IEE showing that intelligently-controlled battery storage at substations could enable grids to accommodate up to 150 GW of additional solar capacity—more than current German installed PV capacity of 130 GW. The study analyzed real operating data from 20 transformers across 13 substations and modeled potential with large-scale battery storage.

      „Intelligent gesteuerte Großbatteriespeicher können Solarstromspitzen genau dann aufnehmen und die Energie später wieder abgeben.“ „Dadurch müsste im Jahresdurchschnitt nur rund ein % des zusätzlich erzeugten Solarstroms [...] abgeregelt werden“, erklärt der #BSW-Solar.
